To keep below two degrees, we will most likely need to limit atmospheric concentrations of carbon dioxide (the The Inter-governmental Panel on Climate Change (IPCC), a most prevalent greenhouse gas) to between 350 and 430 collaboration of the world’s pre-eminent climate scientists, parts per million. Before industrialisation, the concentration has found that the evidence of a warming world is now was around 280 parts per million. Now, our burning of fossil “unequivocal”. It is “very likely” that human activity has fuels has driven it up to 383 parts per million and the figure caused “most of the observed increase” in average global rises every year.

Average global temperatures rose by 0.6 degrees in the 20th century and the greenhouse gases already in the atmosphere mean some further warming is inevitable. We can’t stop climate change from happening. Our challenge is to stop it getting even worse.

These would be a climate disaster. 4 6 Northern brown argus by Mark Hamblin Signs of change in the natural world Climate change poses a grave threat to all life on earth.
